2008 sts 3.6 l di{ reduced engine power}

Good day all cady owners,

The first thing to do is check trouble codes. If you can't limp the thing to AutoZone where they'll check the codes for free you can buy a cheap CAN enabled code reader that will read the engine codes at almost any parts store or Walmart.

Hi belushi! I'm sorry you've been having these frustrations and wanted to let you know I'm on hand if you would ilke me to check for open recalls on your STS or check the exact expiration dates/mileage for your warranties as well. Please feel free to email me anytime at Katie_Lucille@gmexpert.com for further assistance.

If there is a difference between commanded throttle position and actual position it will go to reduced power mode. My CTS used to do it all the time when -40F weather would hit. All I had to do to clear it was shut it off and restart it.

My advice is to pamper the V6. Take no chances. If your insurance doesn't have towing, add it.

Get a good code reader if you go that route. These cars have body & suspension codes as well as engine. I'd just have it flat-bedded to a delaer. Once at a dealer, they can validate the valve timing and the chain/guide wear. If that passes muster and your oil rings are OK, you're cool.

Wow , this is a cool forum , i didnt think that i would get so many useful replays that quick.
Actually the car is not salvage it is ammaculate, but been laying for a long time , it was my late aunti car which she bought it new in 2008 but unfortunatly died 4 months later, and i just took the car few months ago and put nearly 6k enjoyable miles on it, the tyres are original with 2 different sizes back and front 18 rims (make noises when first drive the car for few minutes).
the warranty expired last august (4 years or 60k KM) i live in BAHRAIN so the warranty is less here unless you buy extended warranty on purchase day.
I had Jeep grand cherokee overland hemi engine which i bought it second hand 3 years ago and bought jeep extended warranty till 100k km, the car was 2007.
but as i said cady dont offer that.

sorry to make it long, i took the car to the dealer and i will keep you posted with the outcome.
bytheway i used to be a member of this forum when i had the monster 95 northstar sts 6 or 7 yrs ago and it was very useful and enjoyable (i miss my 95 sts).

good day all,
The agent informed me today, it looks like the fuel pump failed and needs replaced + the fuel pump sensor+fuel lines+6 injectors where they have to remove the
manifold to replace them (direct injection) plus other few gaskets and sensors.
the agent doesnt know why this happened at this low mileage.
i think since the car was laying for a long time all the dirt and dust etc. blocked all the fuel systems.
ithe agent will inform me about the cost which thwy thing will be heavy $$4,000 approximate, most of it is labour cost.

usually when fuel pump fails it gives you a warning by cutting and jettering etc, and not suddenly.
